FAQ
Yes, all of our hydraulic brakes are designed with the riding habits of most local people in mind.
The hose has been prefilled with mineral oil and can be used directly without refueling.
After installing our 180mm brake discs and brake base, it fits most models.
They cannot be used universally. The brake pads used by our hydraulic brakes are independent models, brake pads are larger, thicker and more durable than ordinary brake pads.We have a separate model (MT600) of brake pads for sale in our store.
I now have great braking with almost no pressure on the levers.
The standard brakes on my PVY Z20 Plus were not that good to start and getting to be lethal.
Prodotto ottimo , ma cosa più importante, la dy-island si è dimostrata una ditta di alto livello e attenta alle esigenze del compratore… mi ha sostituito una pinza che sfortunatamente avevo danneggiato , gratuitamente, seguendomi passo passo ad ogni mia richiesta di aiuto via email. La consiglio vivamente
Absolutely great price/performance ratio, since then I've ordered one for my other bike and my bike mechanic has also ordered one for another bike. The kit had all the necessary adapters and whatnot needed to install. I might shorten the hose though.
I have the two piston styles of dyisland brakes on my ebike. I changed the front because it was constantly leaking the fluid. I bought the 4 piston Ld4x and it made a big difference with braking power.
If the price is right I may upgrade the rear brakes with the LD4X soon.
Installed on Radrover 6 Pro after failing to bleed stock brake.
Works great, excellent value. Had to zip tie cord to frame but no problem.
Équipement de bonne qualité. J'avais besoin de freins à 4 pistons pour remplacer ceux à 2 pistons sur mon vélo Wildeway FW11S 3.0. Mon poids élevé de 275 livres était trop demandant pour les plaquettes qui s'usaient trop rapidement.
Have a very good braking effect, I am very satisfied
This break works very great, i like it, recommended
This is real value for money. Well engineered. I had to return it because I ordered the 180mm kit and it was too big. I'm exchanging it for the 160mm kit.
Easy install. Had to swap the brake light cable which was easy. All around good experience.
Needed replacement brakes. Customer service was very courteous, helpful and prompt.
Le kit est est très bien
Mais il est regrettable qu'il ne contienne pas une calle pousse piston et des embouts pour la purge.
Excellent kit. Replaced the dual piston calipers on my Philodo Falcon. Bought the bleed kit as well. Bled the system and my brakes are great.
I have a happy with this brake.
I had a tough time finding Hydrolic brakes for my Amyet Ebike and these were an almost perfect fit. I did have to shorten the front brake lines, it was straightforward and easy.
These brakes, from a mechanics view point, are easy to work on.
Great Hydraulic Braking system.I highly recommend this hydraulic brakes
Came with so much parts
On time and everything looks elegant, fix my bee surron, great! And the best deal and
Was perfect replacement set for our MacFox e-bike. Came with everything needed. Shipping was quick also. Breaks work extremely well, would order again. Thanks
Easy to install and reliable in use. Recommend!
I ordered some brake was sure they was right ... However, before they sent them they emailed me asking my bike make. And I was wrong they refunded me immediately. So I could get the correct one. That's something not many companies do any more so this is where I want my business to be through. Ty and caring about my safety and wallet.
Hello , as usual dyisland quality nothing bad to say beautiful and powerful not expansive , I recommand without hesitations !

very satisfied with the brake set. easy to install and works well.
Hola pues la verdad que cambié el equipo de frenado antiguo de vuestra marca con dos pistones por el nuevo de cuatro pistones, pero me encontré con la sorpresa de que he tenido que aprovechar el cable antiguo para detener el motor, porque el cable corto de dos pines no me servía Les pregunté en la página web pero nunca me contestaron
Everything was ok! I have nowVery good brakes on my Fatbike. Thanks!!!
